To all whom; 'it may concern:

Be it. known that I, HUGH BLACK GornpAisD, a citizen ofthe United States, resid- 1n Staate of Colorado, hanfmvented certain new and useful Improvements in Fastening'Devices for Slabs for Walls, Ceilings, &c.; and

- I do declare the following to be afull, clear,

and exact description of theinvention, such as will enable others skilled inl the art to which it'appertains to make and use the same, reference being had to the accompanying drawings and to the letters and figures of reference marked thereon, which form a partof this specification.

My invention relates to improvements in l slabs for walls of the general class set forth in my previous patents numbered 669,041 and 815,513, and dated Feb. 26th, 1901 and March 20th, 1906, respectively.

'In my improved construction I make the slab orsection having embeddedtherein a fasten' bar and also having another fastening evice which is connected at one extremity with the said bar and at its opposite extremity to the studdings or supporting structure of the building. The latter fastening devices may be connected in such a manner as to permit a sliding movement in a vertical direction, or they may be pvotally connected by means of a. universal ioint to permit a movement in either direction.

Having briefly outlined my improved construction, I will proceed to describe the same in detail reference being made to the accompanying drawing in Iwhich isillustrated' an embodiment thereof.

I n this drawing, Figure l is a frontview of a supporting 'wall showing a number of sections of my improved wa1l1n place. Fig. 2 is a horizontal' section taken on thev line 2`2 Fig. 1. Fig. 3 is a similar section, showing a diierent supporting means for the slab and a diii'erent manner o: f connecting the fastening devices.` Fig. 4 is a vertlcal section -taken on the line 4-4 Fig. 2. Fig. 5 is a similar section taken on the line 5-5 Fig. 3. Fig. 6 is a rear -fa'ce view of Fig. 5 or a view looking in the direction of 'arrow 6 in Fig. 5. Figs. 7 and 8 are vertical sections taken through `the wall showing different means for fastening the slabs in place. Fig. 9 is a section taken ou the line 9-9 Fig. 8. Fig. 10 is a section similar to Figs. 7 and 8 showing still another fastening means. Fig 11 is a horizontal section taken on the in thecity andfcounty of`Denver and.

line 11-11 Fig. 10. Fig. Y 12 is a section taken on the line 12-12 Fig. 13' viewed the direction of the arrow. 4. Fig'. 13'is ahorizontal section taken on` the line l3-A13.Fig. 12. Fig. 14 is a view similar to Fig. 12 but showing .a ldifferent construction of fastei i ingnieans. Fig. 15 is a. section taken on the line 15-15 Fig. 14.

The same reference characters indicate the same .parts in all thefviews.

Let the numeral 5 designate -sections of the Wall. These sections may consist of slabs of any desired shape or surface area. In'

Figs. 1 and 2 thesevsections 5 are secured to a wall 6 having vertical ways 5? referably composed ofvertically disposed tu es cast in the wall and provided withslots 8 open frontand provided with enlargements 9, to

receive heads l0 of'bolts 12, which bolts have-their opposite extremities cast inthe sections and entirely concealed in front. As

fshown in Fig. 2, the threaded extremity of the bolt is passed through a bar 13 which is bifurcated where the bot enters it, a washer 14 and a' nut 15bein connected with 'he bolt in the rear of the ar. These boltsare connecteddgwithl the bars, andthe latter. are supported in position in the mold'at the time the sections 5 are manufactured. In* this event the sections are provided with the bolts 12 protruding from their rear faces and adapted to enter openings 9 of the ways 7.-

n constructing the Wall the sections are so l '90 in openings 9, the sections are allowed to arranged, that after inserting the bolt heads niove so that. the bolts will be oii't of register with the openings 9, whereby they are held securely in place. In Fig. 2 of'the drawing the tubos 'forming the Ways T are approximalcly triangular in cross section. lIt is evident, however, that these 'tubes may be of 1 any desired shape-in cross section, whereby they areI adapted 'to\ fit bolt heads of any shape. The construction just vdescribed is shown on a larger scale in Fig. 4. The sections are preferably provided with a layer of wire mesh 16 suitably located.

ioo

In Fig. 3 vertically disposed channel bars ile 'lhe hall auth `The 'shank' of the bolt protrudes'from the section in the rear and a nut- 21 may be appin 33 which thejsection may move downwardly unt plied thereto. The channel bars 17 are preferably (provided with enlarged openings 22 adapte to receive the nut extremity of the bolt. From these openings, slots 23 extend. These slots are of suicient width to allow the shank of the bolt to pass freely, but too narrow to allow the nut 21 -to pass. Hence afterthe nut is inserted in the openino' 22,

il-the nut is locked in place, thus securely holding the wall section in"place.

' As shown in` Fig. Sbof the drawing, the vert-ical edges 'of the wall sections are pro-x vided with V-shaped tongues and grooves designated A and B, respectively. These vertical edges, however,'may be united in any suitable manner.

'In the form of construction shown in Fig. 7, the wall section is molded with a rod 24 in place and intersecting the socket 25 open in 'the rear, the said rod being bent outwardly in the socket as shown at 26 and into which a fastening bolt 27 may be hooked. 'lhis boltas shown in the drawing is providedv witha nut 2S, and may be used in connection with any suitable support.

In the form of construction shown in Figs. Si and 9, a bar-29, T- haped in cross sectl ion is illustrated. This bar intersects a socket 30 opened in the rear and in which is-located the bifurcated extremity 32 of a bolt 31 whose threaded shank -protrudes rearwardly. TheA bifurcated end of this bolt straddles the central member o'f the T- shaped bar and is connected therewith by a (passes through registerin openings forme in the bifurcated part o the bolt and the central member of the bar, whereby the bolt is'pivotally connected with the, bar. The socket 30 is of sutiicient size to ermit the" bolt a limited degree of oscillating movement, to allow for the settling of n the wall 'ndependently of the support or vica1 versa,\-without cracking or injuring the wa In the form of construction shown in Figs. 10 and 11, a flatbar 34 is embedded in the wall section and provided with a vertical slot 35 adapted to receive a pin 3Q which alsol asses -through the bifurcated arms 37 of a iiolt 88 having a lrearwardly protruding shank 39. On opposite sides of the bari-14 are located disks 40, the said.V disks being located between the bar andthe arms 37 of the bolt. This b0lt438 permits an oscillating and also a .vertical movement, the rearward opening 42 leading to the socket 41, being suiciently elongated to permit the bolt to move vertically bodily if circumstances should require.

In the form of construction shown in Figs. l2 and 13 a bar 43 is cast in the slab or secdevices heretofore explained 1 i l I tion and provided with a rectangular mexnber 44 through which'upasses two `pins 45. In this member-44 is' located a socket 46 provided' with a metal lining 47, said socket being open in the rear as shown at 48. The pins 45 are located intermedia-te the top and bottom of the socket and are adapted to receive the double hooks 49 of a bolt 50 whose threaded extremity protrudes rearwardly from the slab or'sectlon. 'ln molding this slab, the cavity or chamber 46 is left open in the rear. so that the fastening bolt 50 may be inserted and connected with the By virtue of this construction the bo ts need not be in position when the slab is manufactured, since there is room enough between the twopins 45 to insert the'hook-sha ed extremity of-the bolt when turned so t at the hooks shall occupy a position vat right angles to that shown in Fi 13. After the bolt head has been inserte in the positionstated, by giving it a quarter turn it will be i the position shown, in the last named gure, whereby it engages the pins 45 and is held securely in place for-fastening purposes. y l r In the form of construction shown in Fig. 14, a bar 51 provided with a rectangular member 52, is embedded in the section or slab when the =arne `is manufactured. This member 52 is lm ted in a chamber 53 opened in the rear as shownl at 54, the said chamber being provided with a metal lining 55.- Before the slab is manufactured, thehead 56 of a bolt 57, is trunnioned in the opposite sides of the member 52. ,'.s shown m the drawing the bolt head is trunnioned in the member 52 on opposite sides The shank of this bolt thus protrudes rearwardly from the slab after the latter is manufactured. v y -itrom the fore oing description the use of my improved s ab will be readily understood. It may be employed for ceilm and floors as well as vertical or other wal s, and it may be connected with any suitable support, andby any of the various fastening as well as others of similar character.
